Q

What is a deep vein thrombosis?

A
  • A deep vein thrombosis is the formation of a thrombus within a deep vein, most commonly the deep calf veins
  • It produces an inflammatory response (calor, dolor, rubor, tumor, functio laesa)
21
Q

What is bronchopneumonia?

A
  • Bronchopneumonia is an inflammatory condition of the lungs, primarily affecting the alveoli and caused bacteria/viruses.
  • It has a patchy distribution and generally involves more than one lobe and often both lungs (seen in young & old patients)
22
Q

What is scurvy?

A
  • Scurvy is a disease which results from a deficiency of vitamin C which is required for hydroxylation of procollagen
  • Defective collagen production presents with impaired wound healing and bone formation, fragile capillaries, resulting in abnormal bleeding
23
Q

What is familial adenomatous polyposis?

A
  • FAP is an autosomal dominant inherited condition in which numerous adenomatous polyps form mainly in the epithelium of the large intestine
  • While these polyps start out benign, malignant transformation into colon cancer occurs when they are left untreated
24
Q

What is chronic granulomatous disease?

A
  • Chronic granulomatous disease is a genetic condition wherein phagocytes cannot form superoxide and initiate a respiratory burst.
  • This results in many chronic infections in the first year of life as well as the formation of numerous granulomas and abscesses affecting the skin, lymph nodes, lung, liver and bones
25
Q

What is sarcoidosis?

A
  • Sarcoidosis is a rare condition of unknown cause which causes granulomas to develop in the organs of the body
  • It usually affects the lungs and skin
26
Q

What is a thrombosis?

A

A thrombosis is the formation of a solid mass from the constituents of the blood, within the circulatory system

27
Q

What is Von Willebrand’s Disease?

A
  • Von Willebrand’s disease is a relatively common autosomal dominant disease often due to a reduction in vWF production
  • There is abnormal platelet adhesion to the blood vessel wall as well as reduced FVIII amount/activiy
28
Q

What is α1-antitrypsin deficiency?

A
  • α1-antitrypsin deficiency is an autosomal recessive disorder resulting in low levels of alpha-1 antitrypsin, a protease inhibitor which deactivates enzymes released from neutrophils at the site of inflammation.
  • Patients develop emphysema as proteases released by neutrophils within the lung destroy normal parenchymal tissue
29
Q

What is atherosclerosis?

A

Atherosclerosis is the thickening and hardening of arterial walls as a consequence of an atheroma

30
Q

What are malignant neoplasms?

A

A malignant neoplasm is an abnormal growth of cells that persists after the initial stimulus is removed and invades surrounding tissue, potentially spreading to distant sites

31
Q

What is chronic gastritis?

A
  • Chronic gastritis occurs when the stomach lining becomes inflamed, often due to bacterial infection by Helicobacter pylori
  • It can be painless or cause dull, persistent stomach pain
32
Q

What is a neoplasm?

A

A neoplasm is an abnormal growth of cells that persists after the initial stimulus is removed

33
Q

What is an atheroma?

A

An atheroma is the accumulation of intracellular and extracellular lipid in the intima and media of large and medium sized arteries

34
Q

What is a stroke?

A

A stroke is a rapid onset of cerebral deficit (usually focal) lasting more than 24 hours or leading to death, with no cause apparent other than a vascular one

35
Q

What is Ehlers-Danlos syndrome?

A
  • Ehlers-Danlos syndrome is a heterogeneous group of 11 inherited disorders due to the defective conversion of procollagen to tropocollagen
  • Collagen fibres lack adequate tensile strength, hence the skin is hyperextensible, fragile and susceptible to injury and joints are hypermobile
36
Q

What is chronic cholecystitis?

A
  • Chronic cholecystitis involves repeated episodes of acute inflammation of the gallbladder
  • It usually occurs when a gallstone blocks the cystic duct
37
Q

What is wet gangrene?

A
  • Wet gangrene is necrosis that has been modified by infection with a mixed bacterial culture
  • The underlying process is liquefactive necrosis
38
Q

What is chronic hepatitis?

A

Chronic hepatitis is defined as over 6 months history with histology of inflammation and necrosis in the liver

39
Q

What are myelomas?

A

Myelomas are malignant neoplasms of plasma cells

40
Q

What is an ischaemic stroke?

A

An ischaemic stroke is a stroke secondary to a reduction or cessation of blood flow to a localised area of brain due to arterial occlusion or hypoperfusion

41
Q

What are pressure sores?

A
  • Pressure sores are ulcerated areas of skin caused by continuous pressure from the weight of the body on that area resulting in skin ischaemia
  • Skin compression leads to damage of the underlying tissues and blood vessels, commonly occurring over bony prominences e.g. heels, sacrum, elbows, hips
42
Q

What are leukaemias?

A

Leukaemias are malignant neoplasms of blood-forming cells arising in the bone marrow

43
Q

What is a paraneoplastic syndrome?

A

Paraneoplastic syndrome is a disease or symptom that is the consequence of the presence of cancer in the body, but is not due to the local presence of cancer cells

44
Q

What is dry gangrene?

A

- Dry gangrene is necrosis that has been modified by exposure to air

  • The underlying process is coagulative necrosis
45
Q

What is Disemminated Intravascular Coagulopathy?

A
  • DIC is a type of microangiopathic haemolytic anaemia due to the pathological activation of coagulation
  • Numerous microthrombi are formed in the circulation which leads to consumption of clotting factors and platelets and a haemolytic anaemia
46
Q

What is a tumour?

A

A tumour is any clinically detectable lump or swelling

47
Q

What is a haemorrhagic stroke?

A

A haemorrhagic stroke is a stroke secondary to bursting of a blood vessel, often seen in hypertension

48
Q

What is a pulmonary embolism?

A
  • A pulmonary embolism is a sudden blockage of a pulmonary artery in the lung, usually due to a deep vein thrombosis
  • It presents with chest pain, shortness of breath, coughing and blood stained sputum
